在一个数组中绘制棋盘游戏块

我无法获取数组来显示白嘴鸦或主教（r & b）。我需要将它们显示在King（k），G，s，n，l前面的一排上。案例陈述应该贯穿并绘制棋盘上的所有棋子，但它只能运行18次，然后崩溃，但我相信我宣布阵列有40个棋子（在将棋中每个棋手都以20个棋子开始）。此案件陈述也忽略了案件r和b。在一个数组中绘制棋盘游戏块

Here TheArray is only called 18 times, I was told this is because I only have 18 spaces in the array, and it then crashes because there is no more room. It calls the back row of pieces and the pawns, ignoring the rook and bishop; and never getting to the second player

错误日志将非常感激 – Triode 2012-03-01 14:48:13

有没有一种办法格式化错误日志，当我发布？目前它只是出现在一条大线上，而且很难阅读。 @slayton 我重新编写了代码，并尝试更改一些值，但似乎没有为我尝试过的方法工作 – 2012-03-01 14:53:14

将整个堆栈跟踪复制并粘贴到一个代码块中 – slayton 2012-03-01 15:17:40

应该这样：

pieces[(20 * i) + 10] = new Piece('r', i, i3, (7 * 1));

是这样的：

pieces[(20 * i) + 10] = new Piece('r', i, i3, (7 * i));

此外，片0到10的instered在pieces，但你覆盖9和10（你的b和R件）与棋子。

建议，你为什么不创建一个int pieceNum，然后使用：

pieces[pieceNum++] = ...

，而不是计算偏移。

我甚至没有看你的构造函数参数，因为你没有发布那个类。计算pieces阵列的偏移量时有足够的问题。

在此代码的第一通（当你外我变量= 1），看看OFFSET（在评论）：

pieces[20 * i] = new Piece ('K', i, 4, (8 * i)); // OFFSET = 0 
pieces[(20 * i) + 1] = new Piece('G', i, 3, (8 * i)); // OFFSET = 1 
pieces[(20 * i) + 2] = new Piece('s', i, 2, (8 * i)); // OFFSET = 2 
pieces[(20 * i) + 3] = new Piece('n', i, 1, (8 * i)); // OFFSET = 3 
pieces[(20 * i) + 4] = new Piece('l', i, 0, (8 * i)); // OFFSET = 4 
pieces[(20 * i) + 5] = new Piece('G', i, 5, (8 * i)); // OFFSET = 5 
pieces[(20 * i) + 6] = new Piece('s', i, 6, (8 * i)); // OFFSET = 6 
pieces[(20 * i) + 7] = new Piece('n', i, 7, (8 * i)); // OFFSET = 7 
pieces[(20 * i) + 8] = new Piece('l', i, 8, (8 * i)); // OFFSET = 8 

for (int i3 = 0; i3 < 2; i3++){    
    pieces[(20 * i) + 9] = new Piece('b', i, i3, (7 * i)); // OFFSET = 9 for both bishops, the 2nd overwrites the 1st 
    pieces[(20 * i) + 10] = new Piece('r', i, i3, (7 * 1)); // OFFSET = 10 for both rooks, the 2nd overwrites the 1st 
}   

for (int i2 = 0; i2 < 9; i2++){    
    pieces[(18 * i) + 9 + i2] = new Piece('p', i, i2,(6 * i)); // OFFSET = 9 thru 16, overwriting the bishop and rook set above 
}

谢谢，我只是注意到了我自己。虽然我不知道它是如何成为1 ... – 2012-03-01 15:02:43

@OneGlove还有更多，检查编辑 – tcarvin 2012-03-01 15:03:22

我认为b和r的（7 * i）会显示在棋子上方的行中，或者我需要用i3移动for循环的右括号？ – 2012-03-01 15:07:12
